CLOTH-BEAM FOR LOOMS.

Specification of Letters Patent.

iratentea oet. is, 1ero.

Application led January 13, 1910. Serial No. 537,814.

State of Massachusetts, have invented an Improvement in Cloth-Beams for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to cloth beams for looms.

rThe aims and purposes of the present invention are primarily to provide means l5 whereby the present difficulty experienced in ,removing the cloth from the beam on which it has been wound as it was woven may be overcome.

Other objects of the invention will later appear in connection with the following description and accompanying drawings of one form of means for carrying the invention into practical effect.

in the drawings, Figure 1 is a front View of the cloth beam and so much of the associated loom parts as are desirable to make clear the present invention; Fig. 2 is a vertical longitudinal section passing centrally through the cloth beam and its supports; is a transverse section on the line 33, Fig. 1; Fig. 4 is a transverse section on the line 4 4, Fig. l; and Fig. 5 is a transverse section on vthe line 5 5, Fig. 1.

The loom frame may be of any usual or desired character and as shown the stands 1 at either side of the loom are provided with bearings 2 for the sand roll 3 mounted on the shaft 4, which may be driven from an suitable source of power transmitted throng i 'the gear wheel 5 secured to said shaft, or by clutch being provided with driving connections with the cloth beam, to the end that the cloth beam may be frictionally driven, as will be clear. In the present instance one convenient form of such clutch comprises a member 7 fast to the shaft in the manner stated, the other member 8 being frictionally engaged therewith, as by the adjusting device 9, and having the sprocket a wheel 10 which is engaged by the sprocket chain 11 passing about another sprocket wheel 12 secured to the stud shaft 13, Figs. 1 and 2. Obviously the connection between the shaft 4 and the stud shaft may be variously changed and other forms of fric-- tional drive for the stud shaft be employed within the true scope of the present invention.

The stud shaft 13 is preferably carried by a bearing member 14 adj ustably connected to one of the stands 1, by means of bolts 15 or otherwise, and has secured thereto a cloth beam dri ver. In its present form, this driver is shown as a disk or member 16 screwthreaded or otherwise suitably fixed to the stud shaft 13 to rotate therewith, a spacing collar 17 being interposed between it and the member 14. The driver 16 has a bearing portion 1S which extends into the interior of the cloth beam 19 when the beam is in winding position, and a lug portion 20 which eX- tends through the slotted end of the cloth beam, Figs. 2 and 5, and has a recess 21 for a purpose presently to be described. At its opposite end the cloth beam, when in winding position, is supported by a disk 22 having a portion 23, Fig. 3, to extend into the end of the cloth beam, said disk 22 being sustained on a pin carried by a bearing 26. The pin 25 may be sustained in any suitable manner, but as one convenient support to prevent binding there is provided a bracket 27 having an outer and an inner bearing portion 28 and 29, Figs. 1 and 2, through which the pin may pass, said portions 28 and 29 being oined by a connecting web 30. A bolt 31 may conveniently maintain the bracket 27 in supporting position on the stand 1. A. spring interposed between a fixed part, such as the stand 1 and the disk 22, normally maintains said disk pressed toward the driver 16 at the opposite side of the loom frame, a pin 33, or other means, serving to limit the movement responsive to the said spring.

From the construction thus far described it will be noted that the cloth C, Fig. 1, after passing about or over the sand roll 3 is wound on the cloth beam, which is itself driven by suitable friction driving means in order that as the roll of cloth increases in size on the cloth beam the surface speed or winding action may accommodate itself to the rate of cloth production. It will likewise be noted that the cloth beam may be readily put in and taken from the loom by simply placing one end against the yielding disk 22, forcing the beam endwise to the left, in the illustration, until the opposite end may be seated on the driverl, whereupon the spring maintains the beam on its supports and driver.

As well understood by weavers and those skilled in the art, much ditliculty is'experienced and much time lost in removing thel cloth roll from the cloth beam after it has been wound thereon. The present invention contemplates a simple expedient whereby the cloth may be easily and readily taken from the cloth beam without being unwound therefrom, one form of which is indicated in the drawings.

Extending longitudinally of the cloth beam when it is in winding position is a cloth releaser or rod 3i, the cross-sectional dimensions of which in two directions are unequal, Figs. 3, 41 and 5. That is to say, the releaser or rod 3st is more or less flattened so that the diameter in one direction is less than the diameter in another direction. At one end the releaser or rod 3st has a portion which extends transversely of the cloth beam 19 when the parts are assembled, as in Figs. 2 and 3, said portion 35 passing through a slot 36 in the end of the cloth beam and preferably engaging any one of a series of cross recesses 3T in the disk 22, the construction being such that the portion 35 of the cloth releaser or rod 34 serves to lock the cloth beam and disk 22 from relative rotation. The opposite end 38 of the releaser or rod 3i preferably extends beyond the opposite end of the cloth beam and engages the notch 21 in the lug Q0 of the driver 16, Figs. 2 and 5, the construction being such that the driver 16, the beam 19, and the end of the releaser 34 are maintained in fixed position and are locked so that they rotate together.

From the construction described it will be seen that when the cloth beam and cloth releaser are in operative position in the loom, the end of the cloth 39, Fig. 4t, passes about the releaser which is then supported with its greatest. cross-sectional dimension extending outward or substantially radial of the cloth beam, with the portion 85 of the releaser passing transversely of the beam through the slot 36 and into one of the recesses 37 of the disk 22. The other end of the releaser engages the recess 21 of the lug 20 which extends through the notched edge portion of the beam. Upon rotation of the cloth beam in the manner hereinbefore described the cloth is wound tight about the cloth beam and releaser, substantially as indicated by Fig. 4:. W'hen the beam has been suli'iciently loaded or wound with cloth, it is pushed to the left, Fig. 2, the end adjacent the driver disengaged and carried outward and the beam with its load thus removed from the loom. The releaser is thereupon turned to present its least dimension radially of the beam, which slackens the cloth and permits the beam to be readily withdrawn lengthwise from the roll of cloth. One convenient way of manipulating the releaser is to raise the beam so that the projecting end 3S of the releaser may rest on the floor. A slight jar will then cause the releaser to move longitudinally to disengage the end portion 35 from the notch 36 in the end of the beam, whereupon the releaser can be readily turned by the use of the part 36 as a handle to bring the smaller dimension of the releaser radially of the beam to loosen the roll of cloth and permit endwise separation of the beam and cloth roll.

lVhile the releaser, substantially as hereinbefore described, may be employed with a cloth beam of substantially uniform crosssectional dimension, it has been found in practice that the beam may be made slightly tapering with good results, the smaller end being preferably adjacent the part 38 of the D releaser when the parts are in assembled relat-ion.

It will be noted, regardless of whether the beam is tapering or not, that the end portion 35 of the releaser not only serves to lock the disk 2:?. and beam rotatively, but prevents the releaser from turning and releasing the cloth roll at undesirable times; in other words, it serves as a lock for preventing turning movement of the releaser. Moreover, in the present invention the cloth releaser requires no special construction of cloth beam, and such releaser maybe locked to the beam in its cloth distending position in various ways.

From the character of the invention herein described in connection with one embodiment thereof, it will be noted that the cloth roll releaser or rod, when in position on the beam, serves to clamp the end portion of the cloth against the plain surface of the beam; or, in other words, the surface of the beam is not countersunk or otherwise marred to receive the rod 34, and yet, by passing the end of the cloth about the rod, as described, all

slipping of the cloth, when the beam is rotated, is overcome, the rod itself being locked to rotate with the beam.
